APPLICATION FILED NOV. 11. 1916.

To all whom it may concern:

Be it known that I, EMIL F. MINET, a citizen of the United States, residing at Allentown, in the county of Lehigh and State of Pennsylvania, have invented a new and useful Shuttle-Pin, of which the following is a specification.

The present invention appertains to shuttles, and relates more particularly to ribbon shuttles or shuttles having pinsupon which the quills or bobbins are mounted removably.

In shuttles now in use, removable pins are provided for the quills or bobbins, the pins being detachable from the shuttles for replacing the quills as they are emptied. These removable pins have been a source of trouble, since they are not infrequently lost,

and they occasionally become loosened and fly out accidentally during the operation of the shuttles, thereby providing a smash with attendant difliculties.

It is the object of this invention to provide a shuttle pin assembled permanently with the shuttle and enabling the quills to be readily applied and removed, without any danger whatever of losing the shuttle pin or the same becoming loosened during the operation of the shuttle.

A further object of the invention is the provision of novel means for mounting the shuttle pin, which can be readily applied to ribbon and other similar shuttles now in use, to carry out the desired results in a satisfactory and el'licient manner.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein Figure 1 is a side elevation of a shuttle having the present improvements embodied therein.

Figs. 2, 3 and 4 are enlarged sectional details taken on the respective section lines 2-2, 3-3 and 44 of Fig. 1.

The shuttle 1 has an opening 2 in which the longitudinal pin 3 is disposed, but instead of seating the terminals of the pin 3 in recesses in the shuttle, this pin is perma- Specificatidn of Letters Patent.

nently assembled with the shuttle. One end of the pin is provided with an eye 4 disposed between a pair of hinge butts 5 with which one end of a small plate or piece 6 is provided, said plate being secured to the shuttle 1 at one end of the opening 2 by means of a screw 7 or other suitable securing element, the shuttle 1 having a recess or cavity 8 receiving the hinge butts 5 and the eye or hinge butt 4 of the pin 3, and allowing said pin to be swung out of the opening toward one side for removing and applying the quills. A pivot or hinge pin 9 is engaged through the hinge butts 4 and 5 to pivotally connect the respective end of the pin 3 with the shuttle 1 at one end of the opening 2.

The shuttle 1 is provided at the other end of the opening 2 with a transversely opening slot 10 for receiving the free end of the pin 3, which when the pin is released, can be swung toward one side out of the slot 10.

A catch 11 formed from sheet metal or other suitable material is disposed transversely of the shuttle at that end of the opening 2 where the slot 10 is located, and one end of the catch 11 is pivoted, by means of a screw 12 or otherwise, to the shuttle 1 beyond the closed end of the slot 10, as seen in Fig. 3. The catch 11 projects below the slot 10 and has an upstanding cam 13 whose shoulder is undercut to provide a hook 14 engageable with the pin 3. The catch 11 is provided at its free end with a lower sleeve 15 receiving one terminal of a V-shaped or doubled wire spring 16 which has its other terminal bent downwardly, as at 17 and engaged or embedded within the shuttle below the opening 2. The terminals or arms of the spring 16 tend to separate, whereby to raise the catch 11 with its cam 13 projecting across the slot 10. The spring 16 has coils 18 at its crotch portion embracing a screw or holding element 19 engaged into the shuttle 1 at the respective end of the opening 2, whereby to hold the spring in place.

When the pin 3 is in place, the catch 11 being raised by its spring 16 will hold the cam 13 across the slot 10, .so that the pin 3 cannot move out of the slot, thereby holding the pin in place. The hook 14 in engaging the pin will also prevent any accidental movement of the catch 11 to releasing posi- Qopie's of this patent maybe obtained for ward one side for removing and replacing the quill. When the new quill is in place, the pin 3 is swung into the slot 10, and in engaging the cam 13 will depress the catch 11, and said catch will snap into place when the pin 3 is moved to the end of the slot 10, the cam 13 snapping behind the pin 3 to prevent its removal from the slot 10 unless the catch 11 is manually released.

Having thus described the invention, what is claimed as new is:

A shuttle having an opening extending from side to side and a transverse slot at oneend of the opening extending from one side to a point short of the opposite side, acatch pivoted to the shuttle between the last mentioned side thereof and the correspond ing end of the slot and projecting along said slot toward the open end thereof, said catch having a cam projecting across said slot and having an undercut shoulder providing a hook, a pin pivotally connected with the shuttle at the opposite end of the opening, the free end 01": the pin being swingable into said slot to be engaged by said cam and hook, a holding element carried by the shuttle adjacent to the pivot of the catch, the catch having a sleeve near its free end opposite to said cam, and a V-shaped spring having one terminal fitting slidably in said sleeve and having its other terminal engaged with the shuttle, said spring having a coil at its crotch portion embracing said holding element, the terminals of the spring projecting in the same general direction as the catch.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
